you will need
2 Allen Keys to remove the air bag ( remove the +ve connection to the battery and leave for 15 mins before attampting) think keys are 5mm
pull the air bag out and there is a wire behind it, pull the connection, it just pops out.
then you will need a big socket and a socket wrench to remove the main nut, think its 18mm (not positive on size)
pull the steering wheel towards you and it should come off without too much fuss.
remember to have the origonal wheel in a streight position to put the new on on streight!
its an easy enough job, just take your time
be care full not to chack the airbag cable when putting everything back together. I chacked mine last week and broke the cable
this brings on the airbag light and you need vagcom to re-set the light one it is on
